Abstract

A key board with a U-shaped piston structure is composed of a key cap, a middle board, a U-shaped piston, round silicon gel, a film circuit, a backlight board and a bottom board. The backlight board is disposed on the bottom board. The film circuit is adhered to the backlight board. The round silicon gel is disposed on the film circuit. The middle board is disposed on the round silicon gel. The U-shaped piston is inserted into the middle board. The key cap is clamped in the upper side of the U-shaped piston. By adopting the U-shaped piston structure, light on the bottom of the key board is not easy to be shielded, so that light transmittance of the body part of the key board can be realized perfectly and light emitting marks on the key cap can be saw clearly. A friction part of a prior key board structure is made of common plastic material, so that friction noise is high. The U-shaped piston according to the utility model is made of oil-based wear-resisting plastic material, so that plastic friction is reduced and a working procedure of adding lubricating oil in the prior art is removed. Compared with the prior art, the key board provided by the utility model has advantages of being good in key cap light transmittance, comfortable in key touch, low in noise, long in service lifetime and the like.

Description

With the keyboard of concave character type piston structure

Technical field

The utility model relates to a kind of keyboard of new structure, is specifically related to the keyboard with concave character type piston structure.

background technology

The piston structure of existing keyboard is square, thereby easily blocks the light source of keyboard bottom, and the brightness of the character emitting above keycap is reduced.In addition, what the square piston of existing keyboard and middle plate adopted is common plastic material, and these parts coefficient of friction is each other larger, and in order to address this problem, traditional way is to add lubricating oil.After lubricating oil is dry and astringent, the comfort level of operation keyboard reduces, and keyboard noise has also strengthened, and the life-span of keyboard has also shortened simultaneously.

utility model content

The purpose of this utility model is to provide the keyboard with concave character type piston structure, is to be mainly used in computer or similarly on equipment, reaches that on keyboard, character emitting is clear, button is comfortable, easy to operate, good hand touch, long object of keyboard life-span.

The utility model is to realize like this, with the keyboard of concave character type piston structure, formed by keycap (1), middle plate (2), concave character type piston (3), circular silica gel (4), thin film circuit (5), backlight (6) and base plate (7), backlight (6) is placed on base plate (7), thin film circuit (5) is attached in backlight (6), on thin film circuit (5), put circular silica gel (4), middle plate (2) be placed on circular silica gel (4) above, during concave character type piston (3) inserts, plate (2) is upper, and keycap (1) is stuck in concave character type piston (3) above.

In the keyboard with concave character type piston structure, a side of concave character type piston (3) has a recess (9).

In the keyboard with concave character type piston structure, the described keyboard with concave character type piston structure, concave character type piston (3) adopts oiliness wear resistant plastic material.

In the keyboard with concave character type piston structure, described middle plate (2), one side has a projection (8).

Compared with prior art, the utlity model has the advantages such as keycap light transmission is good, button is comfortable, noise is low, the life-span is long.

embodiment

Now by reference to the accompanying drawings the utility model is described in further detail.

With the keyboard of concave character type piston structure, wherein keycap (1), middle plate (2) and concave character type piston (3) are plastic cement parts, by design plastic mould injection mo(u)lding.The material of keycap (1) is generally transparent ABS plastic material, and the material of middle plate (2) is common ABS plastic material, and concave character type piston material is oiliness wear resistant plastic material, can select not dragon (PTFE) of match steel (POM) or iron.

Assembling process of the present utility model is to realize like this, first by plate (2) in concave character type piston (3) insertion, keycap (1) is stuck on concave character type piston (3), its internal structure and concave character type piston (3) clamp mutually, middle plate (2) is installed to the upper cover of keyboard, then pack circular silica gel (4) into, spread thin film circuit (5), be loaded on backlight (6), finally load onto base plate (7).

Fig. 2 is the button schematic diagram of existing structure, and Fig. 3 is button schematic diagram of the present utility model.In Fig. 2, the piston of existing structure is square, obviously can find out that in illustrated A district luminous is narrow.B district shown in Fig. 3, due to the recess (9) of concave character type piston (3) one sides, and the projection (8) on middle plate (2) top, luminous obviously strengthens, thereby has increased illumination effect.

In the time press...withing one's finger lower keycap (1), keycap (1) drives concave character type piston (3) under the guide effect of middle plate (2), also moves downward simultaneously, has relative fricting movement like this between concave character type piston (3) and middle plate (2).Middle plate (2) is common ABS plastic material, because concave character type piston (3) adopts oiliness wear resistant plastic material, have the effect of self-lubricating, thereby concave character type piston (3) is during with middle plate (2) relative motion, rub little, noise is low, good hand touch, has extended widely the useful life of keyboard simultaneously.
